78 is an upwardly-extending arm, which is bent at 79 into approximately a right angle and lies both in the fork of the end 73 of the lever 72 and in the slot of the stationary guide 80. The sleeve 77 has loosely secured on its lower side two rollers 81 and 82. An annulus 83 is secured between the faces of the cones 34 and 39 and is also guided and operated by means of the rollers 81 and 82.

84 represents the carriage composed of a vertical downwardly-extending flange 85, having grooved wheels 86 secured thereto and traveling on rails C and D of the stationary frame E. (Best shown in Fig. 5.) The bed of the carriage 84 is composed of a flat horizontal plate 87, preferably made integrally with the vertical portion 85. The forward end of said plate terminates in a hingejoint 88, to which is secured an auxiliary bedplate 89, also terminating in a hinged joint 90. Bed-plate 89 has a rearwardly-extending arm 91 and is capable of being adjusted vertically by means of screw 92, which passes through an extended portion of the bearing 51 and presses on the end of arm 91 to obtain the adjustment. (See Figs. II and V.)

A slot 93 is shown in Figs. 1 and H between the ears of the hinged joint 88. A nose-plate 94, havingv a rearwardly extending arm 94, is hinged at to auxiliary plate 89 and is capable of a vertical swinging movement by means of the lug 95, which is a part of said plate, and extends downwardly through the slot 93 and has loosely connected to its end a link 96. Said link is hinged to lever 97, supported on one end of rock-shaft 98, which is mounted in stationary bearings passing through the flanges 85, of carriage 84. Rigidly secured at the other end of rock-shaft 98 is an arm 99, having an incline 100. Supported by a hinge-joint lOl to an extension-arm 102 of the frame E is a rod 103, having a roller 104 of the standard 139.

and capable of vertical adjustment by means of a screw 105, rotatably secured in stationary projection 106 and bearing against the bottom of said rod 103.

The bearing 52 and gear-wheel 55 are located on nose-plate 94, as also are the guides 110 and 111 and the slotted rest 112, which hold the bowpipe or punty 113 in alincment while the machine is in operation. Gear 114 is secured to the blowpipe or punty, and when the pipe is in position between the small rollers 115 and 116 the gear 114 is meshed into gear 55 of the nose-plate 94.

117 and 118 represent holders on the noseplate, having grooves 119 and 120, in which the blowpipe or punty is placed previous to starting the car forward.

121 represents an overbalanced lever secured to pin 89 on lug 89 on the bed-plate 89 and is operated by long lever 122, secured to a standard on the plate 87 at its fulcrum 123. The rear end of lever 122 is free to be acted upon by the lever-arm 124, while its front end is located so as to act on the lower arm of lever 121.

Lever-arm 124 is pivotall y secured to an upright 125 at the rear end of the plate 87. Adjustably secured at one side of the fulcrum of the lever-arm 124 is pin 126, which engages the face 127 of lever 128, pivotally secured at 129 to an extension-piece 129,which is bolted to rails C and D.

129 is a pin pivotally secured to lever 128 by means of a transverse pivot 129 The other end of said pin has a head 129, which moves horizontally between the slotted flange 129' and the back flange 129 of the arm 129 pivoted at 129 and extending toward the shaft 6 into yoke 130. The yoke 130 has two vertical pins 130*, which engage projections 18 on the braking-clutch 18.

130 is a rod connecting lever 128 and lover 131, the latter pivotally connected at 132 to a stationary support 133, secured to the frame of the machine. The upper end 134 of lever 131 engages the side of one of the horizontal pins 135, which are provided with rollers 136, engaging the inner faces 137 and 137 of the shifting clutch 7. The pins are secured to the yoke 138, which extends in half-circular form around the upper portion of the neck of the shifting clutch 7, and has an arm 140 pivotally secured at 140 to and near the top A rod 141 is pivotally secured to arm 140 of the yoke 138 at 141 and extends forward to a pin 141 which loosely secures it to the lower end of lever 142. Lever 142 is pivotally connected at 143 to standard 144, which is secured to extension B of standard A. The upper end 145 of lever 142 is of a springy nature. A coil-spring 148 is secured to the standard 144 and rod 141.

A laterally-extending arm 146, carrying a roller 147, is secured to the horizontal bedplate 87 and operates the lever-rod 142 in the forward movement of the carriage 84.

a roller is secured.

The flange of carriage 84 has avertical slideway 107, in which moves a slide-block 108, having secured thereto a pin 109, loosely engaged in an eye in an extended portion 26' of the sprocket-chain 26. The lower end of said flange 85 terminates in an arm to which Before starting the machine the blowpipe or punty 113 is placed in the grooves 119 and 120 of the holders 117 and 118, which are located on the nose-plate 94and its extended arm 94. In theoperation of my machine the desired amount of electrical energy required passes through the rheostat 1 and supplies the motor 2. While I have indicated and shown electric appliances for the motive power, still I do not confine myself to that means, as any of the well-known means of running machinery can be used without departing from my invention.

arm 124 toward an observer, looking at Fig..

II, is raised until its descending part presses down on the end of the long lever 122, which causes the other end thereof to move upward, overhalancing the lever 121 andcausing the end ofsaid lever'121 to strike the blowpipe or punty 113 and move it out of the grooves 119 and 120, whereupon it rolls down the inclined faces of the holders 117 and 118 until it lies between the wheels 115 and'116 of the guides 1 10 and 111'on the nose-plate 94 and its extended arm 94.

The gear 114 on blow pipe or punty 113 then meshes with the gear 55 on the nose-plate 94. The lever-arm 124 when raised as above described also removes the pin 126 from contact with the face 127 of lever 128, permitting the braking-clutch 18 to be drawn .by spring 148 out of engagement with the rotatable portion 17 by'means of the pin 129 which is above the pivotalconnec-. tion of lever 128, pulling against the inner face of the slotted flange 129 thereby causing the inner end of arm'129 an'dthe yoke 130 to move forward and-to pull on the pins 130 Said pins pull on the projections 18, which disengage the clutch '18 from the rota: table portion 17 During the operation set forth in the next preceding paragraph the lower end of said lever 128 moves toward the rear of the machine, and it in turn through the connect ing-rod 130 causes the lower end' of lever 131 to alsomove toward therear of the machine, while the upper end 134 of the'leve r moves forward and away from the horizontal pin 135 of the yoke 138. (Best seen in'Fig'; II.) The momentthe pin 126 disengages from sprocket-chain 26.

the face 127 of lever 128'it causes the tension on coil-spring'148 to pull the long lever-rod 141 forward,-and it in turn causes the lower end of the arm and the yoke .138 to move forward, pressing the rollers 136 against the inner face 137 of shifting clutch 7, which causes clutch 7 to move forward until its outer inclined face 9 bears against the inner face 11 of the idler 13. (See Fig. II.) These three operations resulting from the actuation of starting-lever 124 are approximately simultaneous.

Power is now transmitted through gear 4 to I gear 15 and idler 13 and then through clutch 7 to shaft 6, then through shaft 6 to bevelgears 19 and 20, which latter gear turns shaft 21 and small gear 22. Gear 22 transmits power to large gear 23 on shaft 24, which drives sprocket-wheel 25, sprocket-chain 26, and the idler sprocket-wheel 30.

The transmission of power and high speed from the motor to the sprocket-chain, as above described, remains the same until the car 84 has traveled, as below described, far enough forward for the roller. 147 on said carriage 84 to engage the upper end of lever 142. The extended portion 26 of the chain 26,

which is secured to the sliding block 108, as,

shown in FigfI, is now inthe right position relatively for pushing the carriage forward,

and byreferring to Fig. II the proper clutch and gears may be seen for running the I will now describethe forward movement of the car 84. The sprocket-chain 26 moves in one direction only, and the extended portion of the link 26 is always in engagement with the sliding block 108, which by means of the vertical slideway 107moves the carriage 84 forward on the wheels 86. When the car, 84 movesforward to the position indicated in Fig. III, the extension-link 26 is below and in a vertical line with the axis of the sprocket wheel 30. The roller 147 on car 84 is in contact with the upper arm 145 of lever 142 and presses'the lever-arm 145 down, thereby pushing the lower end of lever 142 toward fro the rear of themachine, causinglever-rod 141 to push the yoke 138 back until rollers 136 engage the inner face 137 of the shifting clutch 7, which moves the clutch out of contact with the idler 13 and into contact with idler 14, causing small gear 5 instead of gear-wheel '4 to drive the sprocket-chain 26.

and 15 are smaller than gears 4 and 16, it will be readily'seen that when gear 5 is driving" the sprocket-chain itwill be moving slower 'thanwhen gear'4 is driving"it.- As seen in As gears5 120' Fi IV the carriage has movedforward about two links of the chain 26 from the'position shown in Fig. III and is about to cause the arm 99to ride up on theroller 104 and raise tlie'rea'r end of tlie'nose-plate 94 and also to cause the roller 60'to press down on therod 56 in order to'speed up the sprocket-chain 47.

&

- the blowpipe in this invention is inserted in the molten glass a predetermined distance while revolving and remains in the molten glass during a number of predetermined revolutions, which are governed by the size of the gathering to be made. The winding off of the thread from the gathered glass and also the withdrawal of the blowpipe from the tank are practically similar to hand gathering and its results.

In Fig. V the carriage 84 has traveled to its forward position and the auxiliary bed-plate 89 and the nose-plate 94 are shown as partly entered in the ring-hole F of the tank G. The inclined face 100 of lever-arm 99 is shown as raising the nose-plate 94 to the preferred angle to make the desired gathering. This is accomplished by means of the rock-shaft 98, to which lever-arm 99 and lever 97 are fixed, and the link 96, connecting the forward end of lever 97 and the lug on nose-plate 94.

While it seems that the end of the blowpipe as it rises out of the glass would naturally trace an are, still I have provided means whereby the blowpipe not only revolves during the gathering, but is raised, preferably, as indicated by dotted line H in Fig. V, after the gathering has been made. This I accomplish by the extension-link 26 being in or near the horizontal plane of the axis of the sprocket-wheel while the punty or blowpipe is in the glass. Just before and shortly after the extension-link 26' has passed that plane the end of the blowpipe has no perceptible forward or backward movement, because the travel of the said link is substantially at a right angle to the rails C and D. The inclined. face 100 of the lever-arm 99 slowly rides down the wheel 104, causing the end of the blowpipe as it rises to retreat at a very small angle until the extension-link 26 is about to pass the vertical axis of the sprocket-wheel 30, when the blowpipe describes a quick are and while still revolving is quickly withdrawn in a horizontal position from the tank. The particular path can be determined .or varied as desired to give the gatherer of glass the preferred path by properly designing the inclined or cam surface 100.

During the operation just described the roll 60 on the lower end of the vertical flange 85 of carriage 84 presses downward on the inclined face of the runway 60, which pushes down on the forward end of lever 56, Fig. I, and raises the other end, causing rod 69 to push upward on the forward end of lever 72, while the outer or forked end 73 thereof moves downwardly and inwardly, pulling on the bent portion 79 of extended arm 78, eausing the sleeve 77, surrounding stationary rod 76, to move inwardly. This causes the roller 82 to bear against the outer side of the annulus 83 and move it toward the larger diameter of cone 34 and the smaller diameter of cone 39, thereby increasing the speed of the belt 42, which, through shaft 44, sprocketchain 47, shaft 49, gears 55 and 114, increases the speed of the revolving blowpipe previous to and during part of the gathering of the glass. As the carriage retreats all the speedchanging mechanism gradually returns by gravity to its normal position, thereby decreasing the speed gradually during the winding off of the thread.

The blowpipe 113 having gathered the desired amount of glass and the extension-link 26' having passed around the forward end of the sprocket-wheel 30, the movement of the carriage 84 has been reversed, and it travels backward at the same speed it traveled near the end of its forward movement until the roller 147 is disengaged from the upper end 145 of lever 142, which causes the spring 148 to draw the lever-rod 141 forward, whereupon the cluteh 7 is withdrawn from idler 14 and engaged with idler 13. The speed of the carriage is thereby increased on its return, and when pin 126 of lever 124 strikes against face-plate 127 of lever 128 the pin 129 pushes against the flange 129", which pushes the yoke 130 rearward, causing pins 130 to push the face of the brake-clutch 18 against the revolving part 17, thereby stopping the rotation of the shaft 6.

The said movement of the lever 128 causes the upper end 134 of lever-arm 133 to bear against the rolls 136 on the horizontal pins 135 of the yoke 138 and pushes the shifting clutch 7 out of contact with the idler 13, thereby preventing shaft 3 from driving shaft 6, the various parts of the mechanism being left in the position indicated in Fig. I, which is the position in which the carriage rests before starting, ashereinbefore described. When the carriage returns to the position shown in Fig. I, the blowpipe is ren'ioved and another is placed in the holders 117 and 118, as shown in said figure.

Having described my invention, I claim 1. In a glass-gathering machine, a gathering-tool, a carriage therefor, an endless driving means for the carriage, said driving means traveling in a uniform direction and being so timed that the carriage is practically stationary during the time the tool is in the glass.

2. In a glass-gathering machine, an adjustable bed-plate thereon, a carriage, a tilting nose-plate carried by the bed-plate, a gathering-tool carried by the nose-plate, a rock-shaft having one arm connected to the nose-plate and a second arm adapted to be lifted,'when the carriage is in the gathering position, to dip the gathering-tool into the glass.

3. In a glass-gathering machine, an adjustable bed-plate thereon, a carriage, a tilting nose -plate carried by the bed-plate, a gathering-tool carried by the noseplate, a rock-shaft having an arm connected to the nose-plate and a second arm beveled on one side, and a fixed stop on which the beveled arm rides to cause the tool to, enter. and withdraw from the glass.

4. In a glass-gathering machine, a carriage for the gathering-tool,a driving-shaft, a driven shaft connected with the carriage, a pair of idlers loose on the latter shaft, each having means connected to the carriage and to the shifting clutch whereby, when the tool is making a gather, the driven shaft moves slower a rotatable gathering-tool carried thereon,
